reset check engine light on 1991 Toyota Land Cruiser

reset check engine light is on

Asked by for the 1991 Toyota Land Cruiser
If the Check Engine light is on the computer in your car sees a fault with the emission control system. If the fault has been corrected (say the gas cap was loose and you tightened it the car goes through a particular drive cycle (it may take a week or two) and if it sees no fault it will turn the light of itself, otherwise you need a scan tool to turn off the light, it attaches to a 16 pin diagnostic socket under the dash.
'91 doesn't have OTB plug under dash. (doh!)

Disconnect and reconnect battery.
